MINOR H. FOWLER, OF NEW YORK, N. Y.

iMP ROVEMENT IN LANTERNS.

I Specification forming part of Letters Patent No. 40, 10! dated October27, 1863.

To. all whom it may concern:

Be it known that I, MINOR H. FOWLER, of the city, county, and State ofNew York, have invented a new and Improved Lantern 5 and I do herebydeclare that the following is a full, clear, and exact description ofthe same, reference being had to the accompanying drawings, making apart of this specification, in Which Figure 1. is a side view of myinvention, the lower part of the lantern being in section, as indicatedby theline w 00, Fig. 2; Fig. 2, a horizontal section of the same, takenin the line 3 3 Fig. 1; Fig. 3, a detached view of one of thespringcatches pertaining to the same.

Similar letters of reference indicate correspondin g parts in theseveral figures.

To enable those skilled in the art to fully understand and construct myinvention, I will proceed to describe it.

A represents the glass globe of the lantern B, the metal cap 5 U, theguards, and D the metal band at thebase of the globe A.

E represents the lamp, the upper part of which is provided with aburner, F, having a flat wick-tube,- a, and a serrated wheel and shaft,G, for raising and lowering the wick.

This burner and wick-adjusting mechanism,

are of usual construction, and, therefore, do not require a minutedescription.

1 H represents the base of the lamp, which is struck up or formed out ofa single piece of sheet metal, with a flange or rim, 1), at its edge,and a plane horizontal part, c, to which the lower edge of the lamp E isattached, the part c ofthe base H forming the bottom of the lamp. Thispart 0 of the base H is sufficiently larger in diameter than the lowerpart of the lamp to admit-of openings d being made through it betweenthe lamp and a cylinder, 6, attached thereto. (See Figs. 1 and 2.) Thiscylinder 0 extends upward about as high as the top of the lamp E, and isof such diameter that the band D, at the base of the globe A, may fitinto it. The shaft G extends over the top of the cylinder 0 and projectsa trifle. beyond it, so that the thumbwheel f on its outer end will beat the outer side of the lantern, and a slot, g, is made vertically intothe band D, to receive the shaft G and admit of the band D passing downinto the upper part of the cylinder 0. (See Fig.1.)

By this arrangement the wick may be raised and lowered without detachingthe lamp from the lantern, and by an exceedingly simple means, whichdoes not augment in the least the cost of manufacturing the lantern. Byhaving the base H of the lamp constructed, as shown, out of a singlepiece of metal, with openings d made in it, and the part cof the basemade to serve as a bottom for the lamp,

the cost of construction is very materially reduced. The openings cl, itwill be understood, are for admitting air into the lantern to feed theflame, or supply it with oxygen and prevent the flame being extinguishedby a vertical movement of the lantern. The lamp E is secured in thelantern by means of springcatches I I, which are constructed out of asingle piece of metal, as follows: A strip of sheet metal is slottedvertically a distance rather more than half its length, so as to formtwo legs, it, one of which, i, is secured to the lower part of thecylinder at its inner side, to form a spring, and the other leg, 6,being bent so as to project at right angles through an opening, j, inthe cylinder 0, and bent downward at its outer end to form a button, is,for the thumb or finger to press against. The upper parts of the catchesare bent so as to have a portion, I, nearly at right angles to the leg4, and are then bent upward in an inclined position, as shown at m. Thisupper bent portion of the spring forms the catch, the portions Zcatching over a horizontal flange, a, at the bottom of the band D. Theinclined portions m of the catches admit of the flange n as it ispressed down within the cylinder 0 forcing inward the catches, so thatthe flange a may pass below the portions 1 and the latter be forced overthe former. By constructing the spring-catches I in this manner they mayeach be formed of a single piece of metal and constructed at a smallcost. The trouble of soldering buttons on the catches is avoided, and nomanipulation of any kind required except the securing of the catches tothe cylinder 0.

I do not claim, broadly, the arrangement of airoriflces in the bottom ofthe lantermnor the use of air-tubes in the bottom. The 0011-. structionof such air-tubes involves considerable expense.

Having thus described my invention, whatI may all be formed of a singlepieceof metal,

as specified. a

2. The combination of the springs I I, cylinder 0, and rock-shaft G withthe band D and slot or opening g, all in the manner herein shown anddescribed.
